ABSTRACT:
A stacking-type, multi-flow, heat exchanger includes heat transfer tubes and fins, which are stacked alternately, an end plate disposed at an outermost position of the stacked heat transfer tubes and fins in a stacking direction, and inlet and outlet pipes connected to the end plate. The heat exchanger includes a pipe connection plate provided on the end plate, having a pipe insertion hole formed therethrough, into which at least one of the inlet and outlet pipes is inserted and which temporarily fixes an end portion of an inserted pipe in the pipe insertion hole. The pipe connection plate and the entire heat exchanger may be formed with a reduced size and weight, and the brazing quality between the plate and the pipe may be improved.
